Umsebe ongu-H, eyaziwa nangokuthi amakholomu e-universal noma i-I-beams, yizingxenye eziyisisekelo zesakhiwo ekwakheni nasekubunjiniyelani besimanje. Ingxenye yazo ephambene ifana nohlamvu 'H' noma 'I'. Lesi simo esiyingqayizivele sinikeza isilinganiso samandla nesisindo esiyingqayizivele, okwenza kube yinto ebaluleke kakhulu ekuthwaleni imithwalo esindayo.
Lo mhlahlandlela ophelele uzohlola umhlaba wemisebe ejwayelekile ye-H yaseYurophu. Sizohlola imininingwane, izinhlelo zokusebenza, kanye nomehluko obalulekile wamaphrofayili ayinhloko: izingxenye ze-HEA, HEB, kanye ne-HEM.
Ziyini i-H Beams?
Abakhiqizi bagoqa imisebe ye-H ibe yizingxenye zensimbi ezakhiwe ngesigaba esifana nohlamvu "H." Zakhiwe ngamabha amabili ahambisanayoama-flangekuxhunywe ngokuma okuqondileiwebhuLo mklamo usabalalisa umthwalo ngempumelelo futhi umelane namandla okugoba ngezindlela eziningi. Inqubo yokugoba eshisayo iyakhiqizaInsimbi YekhabhoniUmsebe ongu-H, eveza amaphrofayili ahambisanayo anezakhiwo ezinhle kakhulu zemishini.
Izinzuzo Eziyinhloko Zezakhiwo Ze-H Beam
Umthamo Ophezulu Wokuthwala Imithwalo:Isimo se-H sisabalalisa insimbi kahle, sibeka izinto eziningi kude nendawo ephakathi nendawo. Lokhu kwandisa izakhiwo zamandla abalulekile (umzuzu wokungakhathali kanye ne-section modulus), okwenza sikwazi ukusekela imithwalo esindayo.
Ukuguquguquka:Ifanele amakholomu, imisebe, ama-purlin, kanye nezakhiwo ezahlukahlukene ezihlanganisiwe.
Ukusebenza Kahle Kwezindleko:Ukusetshenziswa kwezinto ezibonakalayo okuncishisiwe ukuze kutholakale amandla kuholela ekwakhiweni kwezomnotho
Ukulula Kokwenza:Kulula ukushisela, ukubhanqa, nokuguqula ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi.
Ukuthembeka Okuqinisekisiwe:Ubukhulu obujwayelekile kanye nokusebenza okubikezelwayo ngaphansi kokucindezeleka
Ukucwila Okujulile: I-European Standard H Beams – HEA, HEB, HEM
Imisebe ye-H ejwayelekile yaseYurophu ihlukaniswe ngokuyinhloko ngokulingana kwayo kanye nesisindo ngemitha. Uchungechunge oluvame kakhulu yile:
Imisebe ye-HEA (Uchungechunge Lokukhanya)
Imisebe ye-HEA ibonakaliswa ngokulinganiselaama-flange amancane futhi amancaneuma kuqhathaniswa nokuphakama kwazo. Zivame ukubizwa ngokuthi “uchungechunge lokukhanya” noma “i-IPE-like” light h-beams kodwa zinama-flange abanzi.
Izicelo Ezijwayelekile:Izakhi zesakhiwo sesibili, ama-purlin, amakholomu alula, kanye nokusetshenziswa lapho kulindeleke khona imithwalo emaphakathi.
Isici Esiyinhloko:Isisindo esingabizi kakhulu ngokuphakama okunikeziwe, okukhuthaza ukumelana nokugoba eduze kwe-axis enkulu.
I-HEB Beams (Uchungechunge Oluphakathi/Olujwayelekile)
imisebe ye-HEB imelelauchungechunge olujwayelekile noma oluphakathi-ugongolo lwe-h oluphakathi, equketheama-flange abanzi futhi ajiyilekunezingxenye ze-HEA zokuphakama okufanayo.
Izicelo Ezijwayelekile:Amakholomu kanye nemishayo ethwala umthwalo oyinhloko ezakhiweni, ozimele bezimboni, kanye namabhuloho. Lolu uchungechunge olusetshenziswa kakhulu ekwakheni okuvamile.
Isici Esiyinhloko:Ukusebenza okuhle kakhulu nxazonke, okunikeza ukumelana okuqinile kokugoba kanye nokucindezelwa, okwenza kube kuhle kakhulu kumakholomu.
Imishayo ye-HEM (Uchungechunge Olunzima)
imisebe ye-HEMesindayo futhi eqinileamalungu omndeni. I-HEM Beams iyi-h-beams esindayo kanye ne-h-beam enomthwalo omningi. Ine-ama-flange abanzi kakhulu futhi ajiyilephakathi kwalaba abathathu, ubukhulu bewebhu nabo bukhuphuke kakhulu.
Izicelo Ezijwayelekile:Amakholomu aqinile ezakhiweni ezinezitezi eziningi, ukwesekwa okuyisisekelo kwemishini esindayo, amaphrojekthi obunjiniyela bokwakha (njengezinsika), nanoma yisiphi isakhiwo esithwalwa imithwalo ephezulu kakhulu.
Isici Esiyinhloko:Umthamo womthwalo we-axial ophakeme kanye nokuqina. Ububanzi be-flange yabo obukhulu buhlinzeka nokuzinza okukhulu ekugoqeni.
Izinto Ezibalulekile Okufanele Uzicabangele Ngokukhetha
Ukukhetha phakathi kwe-HEA, HEB, kanye ne-HEM beams kudinga ukuhlolwa kobunjiniyela okucophelelayo. Izici ezibalulekile zifaka:
Uhlobo Lomthwalo Nobukhulu:Imithwalo ye-Axial (compressive) ithanda izingxenye ze-HEB noma ze-HEM, kuyilapho izimo zokugoba ezihlanzekile zingasebenzisa i-HEA noma i-HEB.
Ubude be-Span:Izikhawu ezinde zivame ukudinga izingxenye ezijulile ukuze kube nokumelana okwanele kokugoba.
Izidingo Zokuzinza:Ukumelana nokugoba (kokubili kwendawo kanye nomhlaba wonke) kuthuthukiswa yiziphazamiso ezijiyile kanye nama-web atholakala ezingxenyeni ze-HEB kanye ne-HEM.
Imininingwane Yokuxhumana:Ububanzi kanye nobukhulu be-flange buthinta ukuxhumana kwe-welding kanye ne-bolting.
Izithiyo Zokwakha:Isikhala esitholakalayo singanciphisa ukujula noma ububanzi besigaba.
Ukuthuthukiswa Kwezindleko Nezinto Eziphathekayo:Umgomo ukuhlangabezana nazo zonke izindinganiso zokuphepha nokusebenza ngesigaba esonga kakhulu, ukunciphisa isisindo sensimbi iyonke.
Izicelo Ezivamile Embonini
Uhlaka Lwesakhiwo:Uhlaka lwezakhiwo eziphakeme zezentengiselwano, zezimboni, nezezindlu.
Ukwakhiwa kwebhuloho:Ama-girders kanye nezakhiwo ezisekelayo.
Ama-Mezzanine Nezinkundla Zezimboni:Amafreyimu okusekela phansi okuphakeme.
Izisekelo Zemishini Enzima:Izisekelo eziqinile zemishini yokucindezela, ama-turbine, kanye nemishini emikhulu.
Izinhlelo Zokubeka Izinto Ezigciniwe:Ozimele abaqondile bokugcina izinto ezixinene kakhulu.
I-Chassis Yeloli Ne-Trailer:Amalungu amakhulu ohlaka olude.
Ishadi le-HEA, HEB, HEM
Isiphetho
Ukuqonda umehluko ocacile phakathi kwezingxenye ze-HEA, HEB, kanye ne-HEM beam kubalulekile ekwakhiweni kwesakhiwo okusebenzayo nokuphephile kanye nezinto zokwakha insimbi.Imisebe ye-HEAnikeza ikhambi elilula lezinto zesibili.imisebe ye-HEBisebenza njengehhashi elisebenzayo elinokuguquguquka kwezicelo eziningi zesakhiwo esiyinhloko.Imisebe ye-HEMukunikeza ukuqina okudingekayo ezimweni ezidinga kakhulu umthwalo osindayo.
Hlala ubheka amakhodi okuklama afanele futhi usebenzisane nonjiniyela bezakhiwo abafanelekayo ukuze ukhethe iphrofayili ye-H beam efanele yephrojekthi yakho ethile. Ukukhetha okulungile kuqinisekisa ubuqotho besakhiwo, ukusebenza kahle kwezinto ezibonakalayo, kanye nempumelelo yephrojekthi.
